Does Cocofloss contain any PFAS?

We are happy to share that Cocofloss is PFAS (polyfluoroalkyl substances) free. Cocofloss is made of polyester fibers (no PFAS) coated with microcrystalline wax, coconut oil, and fragrances, Cocofloss is a safe choice for your smile.

PFAS are manmade water and grease-proof compounds that you've probably encountered when cooking with non-stick frying pans, eating off fast-food packaging, wearing water-resistant clothing, or flossing with teflon-based flosses such as Glide.

Scientists are worried about widespread exposure to PFAS from consumer products as the substances have been linked with a variety of grim human diseases. In a study published this January in the Journal of Exposure Science & Environmental Epidemiology, researchers found that individuals who flossed with Oral-B Glide tended to have elevated levels of PFAS in their body. PFAS concentrations in the body accumulate with exposure over time as the compounds do not biodegrade, and so scientists recommend that we limit our exposure to PFAS where we can.

Katie Boronow, a staff scientist at Silent Spring, says "restricting these chemicals from products should be a priority to reduce levels in people’s bodies.” The good news is that folks can limit their exposure to PFAS by choosing products that are PFAS-free – fry your morning eggs with a cast-iron pan instead of teflon and floss out your breakfast with PFAS-free floss!
